It adopts a three-layer composite coating structure of “bottom fused epoxy powder (FBE) + intermediate adhesive + outer polyethylene (PE)”, which has excellent corrosion resistance and mechanical damage resistance. It is the core selection for harsh working conditions such as long-distance buried oil and gas pipelines.
With straight seam welding structure as the core, it is the key basic component of industrial equipment.It has reliable pressure and corrosion resistance, and is widely used in many industrial fields such as construction machinery, chemical industry, electric power, and new energy to provide support for the stable operation of equipment.
External PE And Internal FBE A...
The sub-coating scheme of “external polyethylene (PE) to protect against external environmental corrosion + internal fused epoxy powder (FBE) to resist media corrosion” is adopted, which is suitable for fluid pipeline scenarios where the external environment and the conveying medium need to be protected at the same time.
External FBE Anticorrosive Pip...
It is coated with a single-layer fused epoxy powder (FBE), which has outstanding chemical resistance and is suitable for scenarios such as non-buried industrial pipelines with a low risk of mechanical damage.
